Meanwhile, stargazers also enjoyed a rare Blue Moon occurrence on Aug. 20; the moon marked the third full moon seen during this quarter of the year.

There are varying definitions for the term blue moon, with one indicating the second of two full moons within any given month, while another refers to a Blue Moon as the third full moon in a season with four-full-moon season.

Nevertheless, a blue moon is a rare occurrence; hence the phrase "once in a blue moon."

While blue moons are rare, they can be predicted to occur every three years or so. The next blue moon is slated for 2015, according to USA Today.
